US Chip Controls Challenged as Nvidia Customers Emerge as Technology Corridor Core

The United States faces an unprecedented challenge to its control over the global semiconductor supply chain, particularly against the backdrop of intensifying U.S.-China technological competition. As a leading global supplier of graphics processing units (GPUs), Nvidia plays a pivotal role in the fields of artificial intelligence, machine learning, and high-performance computing. One of its clients, Megaspeed, operates under the name of a U.S. company but maintains deep ties with mainland Chinese enterprises regarding its actual control, prompting heightened scrutiny from the U.S. government over its import and export activities. Recently, according to a report by the U.S. news website Axios, Treasury Secretary Janet Yellen directly questioned Commerce Secretary Howard Lutnick in the White House Situation Room, demanding that Megaspeed be added to the list of entities of national security concern. This exchange underscores the escalating concerns among U.S. leadership regarding cross-border technology transfers.

Megaspeed’s business model primarily involves purchasing high-performance chips from U.S. suppliers and reselling them to China and other countries, while providing processing, testing, and packaging services in the process. Due to its facilities and human resources in China, many analysts believe the company has become a core node in a “technology corridor,” capable of rapidly funneling advanced U.S. chip technology into the Chinese market. The U.S. government has implemented export controls on multiple Chinese enterprises since 2019 and further expanded the scope of regulation for semiconductor-related companies in 2023. However, Megaspeed has not been included in the official list of entities of national security concern, which typically serves as the primary reference for U.S. export controls. Its absence from this list means that its chip transactions in the United States have not yet been subject to strict restrictions.

Treasury Secretary Yellen’s questioning was not merely an administrative exchange but reflected internal divisions within the U.S. regarding the formulation of semiconductor export control policies. Commerce Secretary Lutnick has stated in numerous previous meetings that adding a company to the national security concern list requires rigorous evidence and procedural review, and that established lists should not be altered lightly. In contrast, the Treasury Secretary emphasized that any risk of U.S. technology falling into the hands of competitors must be identified and restricted promptly. This dialogue reveals the delicate balance the U.S. seeks to strike between economic interests and national security, and it demonstrates that in an era of highly interconnected global supply chains, decisions made by a single department are insufficient to independently address complex technology transfer risks.

If Megaspeed is ultimately added to the list of entities of national security concern, it will have a direct impact on U.S. semiconductor companies. Many chip manufacturers and supply chain partners will need to reassess their transaction terms with the company and may even face the risk of suspending or terminating their partnerships. Furthermore, for China, losing a significant channel for importing U.S. chips will force it to accelerate independent research and development and localized production, further driving technological breakthroughs in the Chinese semiconductor industry. From a global perspective, this move could also prompt other nations to adjust their technology export control policies, forming a more complex network of international norms.

Overall, Yellen’s challenge to Lutnick is not just an administrative confrontation but a microcosm of the core issues the United States faces in its global semiconductor strategy. How to balance the promotion of economic prosperity with the prevention of technology leakage will be a critical challenge for the U.S. government in future international technological competition. In the coming months, Congress and the executive branch will further review relevant policies and may update export controls on Megaspeed and similar companies to ensure that the United States maintains its leading advantage in the global technology sector.
